frequently asked questions
What is R value
The term ‘R value’ is an industry measurement that is used to represent a particular materials ability to resist heat flow.
Any materials which have an identical R value should perform exactly the same. This isn’t always the case. R value testing is done in a laboratory where conditions are kept constant. This unfortunately does not happen in real world applications.
What makes our EPS a better choice for insulation is the closed cell structure can maintain its thermal resistance no matter the ambient conditions at work.
This is something other insulation materials can’t provide.
Do I need insulation?
It is worth investing in insulation for both comfort as well as easing your electricity costs.
EPS provides efficient, cost-effective insulation from sub-zero temperatures (freezer insulation) to the high temperatures around 80°C (on hot water pipes). In the construction and insulation industries EPS is the first choice for performance, sustainability and economy.
